The fp L was announced 10 years later than the NEX-3 and that is quite a sizable gap as far as tech is concerned. Both of the cameras feature the same body design (Rangefinder-style mirrorless).

Before diving right into a detailed comparison, here is a short overview of how the fp L grades against the NEX-3 in regards to portability, imaging, features and an overall grade.

Below is a sample of the gallery pictures for Sigma fp L and Sony Alpha NEX-3. The whole galleries are available at Sigma fp L Gallery and Sony NEX-3 Gallery.

Oftentimes, it is very difficult to visualize the contrast between sensor measurements merely by looking at a spec sheet. The graphic below may provide you a far better sense of the sensor measurements in the fp L and NEX-3.

Clearly, both of those cameras feature different megapixel count and different sensor measurements. The fp L having a larger sensor is going to make shooting shallower DOF easier and the Sigma fp L will give you more detail with its extra 47 Megapixels. Greater resolution can also help you crop photos way more aggressively. The more recent fp L provides an edge with regard to sensor tech.
